Sharon Osbourne's Emotional Day on "The Talk"

It was an emotional afternoon on “The Talk” as Sharon Osbourne opened up about her son’s recent diagnosis.

The mother of two fought back tears while talking about Jack's announcement that he has multiple sclerosis and said, “Jack will actually be here on Wednesday to talk about his diagnosis, but he's great. He's doing really, really good and I want to thank everyone for all their texts and goodwill and love they send to us…”

The 26-year-old revealed the news on Sunday (June 17) that he had been diagnosed with the autoimmune disease that affects the brain and spinal cord. He took to his twitter to say, “Thank you all so much for the kind and inspirational words. It means a lot. Adapt and overcome."

After her emotional discussion, the 59-year-old host said, "And what I'm doing right now is not helping because I'm just feeling sorry for myself, and that is no good. So we just have to think positively and get on with this show that we love."

This announcement comes just weeks after the birth of Jack’s daughter Pearl Clementine.
